Mono power module, based on LM3886 application. He enjoys very high popularity and good reputation even among audiophiles who are “overly sensitive to everything that is integrated”. The LM3886 integrated circuit is based on bipolar transistors. It is equipped with protection circuitry for overheating, overload, and a very useful muting circuit for switching on and…
TPA3116 Class D Amplifier Circuit A small class-D mid-range stereo headset that will be used in car headphones, active speakers, or PC-audio. The amplifier module is based on the TPA3116 circuit comprising two bridged power amplifier channels with common switching, muting and protection circuits. TPA3116 Circuit schematic The TPA3116 power amplifier schematic diagram. The U1…
The lamp used in the project is PCL805 tube. Older Readers may remember it because it was used in the vertical deflection pattern of most tube TVs. Today it can be obtained for free or almost free because it has not found use in today’s acoustic amplifiers built by many enthusiasts. What parameters does this…
LM4952 It is not always necessary to have a high power audio amplifier. It is enough to power the small speakers with much less power. The presented amplifier meets this condition. It has a power of 2 × 3 W / 4 V, and additionally allows electronic volume control. LM4952 The module is based on…
Guitar Amplifier circuit the signal is directed to the tip of the TDA2050. The output power is 25 W with a load of 4 ? (17 W at 8 ?). This block is equipped with an additional “CD / MP3 Player” input and three “Slave Out” outputs (for other terminals or recording equipment), “Headphones” (for…
The amplifier module is based on the TPA2005 chip with a bridged TPA2005 power amplifier capable of delivering up to 8V of almost 1.4W at 5V. Thanks to the small operating voltage (2.5V), it was possible to power the typical Lipo 14500 without additional boosters . The audio signal from the IN jack is fed…
AD8532 Small, high-quality headphone amplifier that works with 32? … 100? low impedance headphones. Ideal as an audio supplement. Headphone amplifier with low-noise, low-voltage AD8532 operational amplifier up to 250 mA. Low-noise power supply with ADP7104 regulator. AD8532 headphone amplifier circuit schematic the power supply input signal from the IN jack is fed to a…
IRS2092 Subwoofer 400W Claas D Amplifier Circuit.The main part of this protection circuit is a transistor FET which is connected in the power supply branch amplifier integrated circuit IRS2092. When applying a positive voltage to the control electrode of the transistor, the ground power supply voltage and the comparator halts the modulation process. The transistor…
2X200W transistor amplifier circuit The aim of this bachelor thesis was to design a low frequency power amplifier for speakers for the purpose of sound public events. Its use therefore determine addressed the concerns of the processing, where required by the supply of sufficient power (at least 200W per channel into a load of 4Ω)…
Amplifier 4×60 Watts. To its solution was first selected integrated circuit LM3886T. The proposal continued the calculations and the election of the additional components of the integrated circuit and the design of printed circuit connections. To the end amplifier was also designed system of active cooling. In the fourth chapter was made the proposal of…
